Abstract

The invention relates to a multipole suppression choke, in particular for data buses, which is distinguished by small dimensions and can be easily produced and handled fully automatically. This is achieved by means of a special shape of the core 1 or 2 in conjunction with a special mount 3 of plastic for the core and a snap-in device 3a on the mount for snapping the core 1 or 2 into the latter. <IMAGE>

Description

In der Technik der Datenverarbeitung stellen Transienten und Hochfrequenzeinstrahlungen in die Datenleitungen ein gravierendes Problem dar. Es ist daher unabdingbar, diese Störungen von den Datenverarbeitungsgeräten fernzuhalten. Dies wurde bisher mit Durchführungskondensatoren, die auch eine induktive Komponente durch Umhüllung des Innenleiters mit magnetisch leitendem Material aufweisen, bewerkstelligt. Da für jeden Leitungszug der oft vielfachen Datenleitungen ein solches Element benötigt wird, ist die Montage aufwendig und damit teuer.In the technology of data processing, transients and Radiofrequency radiation in the data lines is a serious problem Problem. It is therefore imperative to separate these faults from the Keep data processing equipment away. So far this has been with Feedthrough capacitors that are also an inductive component by coating the inner conductor with magnetically conductive Have material accomplished. As for every cable train which often requires multiple data lines such an element assembly is complex and therefore expensive.

Da üblicherweise eine Entstörung mittels Induktivitäten wesentlich wirksamer ist, war es die Aufgabe, Drosseln zu entwickeln, die eine Vielzahl von Induktivitäten auf kleinstem Raum vereinigen und die in die Reihe der üblichen Bauteilekonfiguration passen um Bestückungsautomaten einsetzen zu können.Since interference suppression using inductors is usually essential more effective, the task was to develop chokes that combine a large number of inductors in the smallest space and they fit into the range of common component configurations to be able to use placement machines.

Weiterhin werden an diese Bauteile außerdem die Anforderung gestellt, daß sie einfach zu fertigen sind. Bisher wurden Einzeldrosseln vorzugsweise in Form von Ringkerndrosseln realisiert, die wegen ihrer Kleinheit von Hand bewickelt werden mußten. Als Beispiel sei eine Drossel beschrieben, wie sie heute zum Einsatz kommt. Auf einen Ringkern werden 10 Wicklungen à 20 Windungen aufgebracht, die herausstehenden Wicklungsenden müssen dann händisch an die entsprechenden Kontakte gelegt, wobei die Verwechslungsgefahr außerordentlich groß ist.Furthermore, these components also meet the requirements made that they are easy to manufacture. So far Single chokes, preferably in the form of toroidal chokes realized that hand-wound because of their small size had to be. A choke is described as an example, how it is used today. Be on a toroid 10 windings each with 20 turns applied, the protruding ones The winding ends must then be manually attached to the corresponding ones Contacts made, the risk of confusion extraordinary is great.

Alle diese geschilderten Nachteile werden durch die erfindungs­ gemäße mehrpolige Entstördrossel vermieden.All of these disadvantages are fiction Adequate multipole suppressor choke avoided.

Ein Rahmenkern mit etwa rechteckigen Querschnitt (1) (Abb. 1) oder ein Mehrlochkern mit gleichen Außenabmessungen (2) (Abb. 1) wird in eine Kunststoffaufnahme (3) (Abb. 2 und 3), die eine entsprechende Anzahl von Anschlußstiften (4) trägt, einge­ schnappt. Auf einer vollautomatischen Wickelvorrichtung werden die entsprechende Anzahl von Wicklungen (5) aufge­ bracht, deren Enden gleichfalls an die abgewinkelten An­ schlußstifte (4) automatisch angelegt werden. Die Ver­ lötung erfolgt in einer Tauchlötvorrichtung, wobei das Bauteil jeweils in die Tauchrichtung gedreht wird. Das Rastermaß entspricht den DIL-Normen wie sie für IC′s ver­ wendet werden.A frame core with an approximately rectangular cross-section ( 1 ) ( Fig. 1) or a multi-hole core with the same external dimensions ( 2 ) ( Fig. 1) is inserted into a plastic holder ( 3 ) ( Fig. 2 and 3), which has a corresponding number of connecting pins ( 4 ) wears, snaps. On a fully automatic winding device, the corresponding number of windings ( 5 ) are brought up, the ends of which are also automatically connected to the angled pins ( 4 ). The soldering takes place in an immersion soldering device, the component being rotated in the immersion direction. The grid dimension corresponds to the DIL standards as they are used for IC's.

Falls gewünscht, kann das Bauteil noch mit einem (nicht gezeichneten) Gehäuse versehen werden.If desired, the component can still be used with a (not drawn) housing.
